Can you pm the dxdiag to me? Our offices are closed until monday.
But the problem will be the same, for some reason, the codec does not install on your pc.
Can you play other wmv files?
Another try: there's also a K-Lite Codec Tweak tool in the tools, can you try that out? It can detect broken codecs, and detect broken direct show filters.
If that does not report anything, you can generate text files from your installed filters, that might be interesting too.
You can also disable certain filters, I'd certainly try to disable the ffdshow filter, I had crashes with that one myself in the past.
Hope this helps,
Alex
